Caden and his little sister, Nina, went blackberry picking. Caden helped Nina get started until she had 42 berries. When Caden started picking his own berries, he picked 11 berries per minute while Nina continued to pick 5 berries per minute. Which equation can you use to find \( m \), the number of minutes it took for Caden to have as many berries as Nina? \( 42+5 m=11 m \quad 5 m+11=42 m \) After how many minutes did Caden have as many berries as Nina? Simplify any fractions.
